Here's how to make your own...
1. Purchase and assemble some skinny bookshelves. We got ours at Canadian Tire. You could do this with any kind of book shelf , even thicker ones.
2. Buy some wallpaper that you like and a piece of foam board if you want a gap between the book cases (costs $1.00 at the dollar store).
3. Position your bookshelves where you like them and measure any gap between the two. Cut out your foam board to fit in between the book shelves.Tape in place.
4. Cut your wallpaper to fit. If you need two sheets, attach them where they meet in the centre on the back with some sturdy tape. I used electrical tape but there are better tapes out there. Then tape the paper to the back of your shelves. You could probably use a spray adhesive if you have some.
